In addition, although an example in which the parking lot information includes the entrance information and the site information is shown here, the entrance information and the site information may be acquired as separate information. In this case, the entrance information may be stored in the storage unit 22 in association with the map information.

The route searching means 237 corresponds to the searching means of the present invention, and searches for a route from the starting point to the destination. At this time, the route search means 237 searches for a route according to the user level information. In addition, the route searching means 237 searches for a route from the current position to the entrance of the parking lot based on the parking lot information (entrance information), and on the other hand, based on the parking lot information (site information), Search for a route.

[Operation of information retrieval system]
Next, a route guidance method in the navigation system 1 as described above will be described.
[Skill acquisition process]
In the navigation system 1 of the present embodiment, the user terminal 10 detects the user's skill level in driving technology in advance and transmits the detected skill to the server device 20.
FIG. 3 is a flowchart showing the skill level detection processing for detecting the skill level of the driving technique in the present embodiment.
In this skill level detection processing, the skill level detection means 181 determines whether or not the user who owns the user terminal 10 is driving the vehicle (step S1).
For this determination, for example, the positioning unit 11 may acquire the current position in a predetermined cycle, and it may be determined whether the moving speed calculated based on the position interval is a predetermined value or more. The distance in the section where the acceleration detected by is equal to or greater than a predetermined value may be detected. Further, it may be determined that the vehicle is being driven by inputting an operation signal indicating that the vehicle is being driven by a user operation or that the vehicle is about to be driven.

In addition, the skill level detection unit 181 uses the acceleration detected by the sensor unit 17, the posture of the user terminal 10, the position measured by the positioning unit 11, the sensor unit 17 and the positioning unit 11 while the user is driving the vehicle. The time at which the detection process is performed is acquired, and these are associated and stored in the terminal storage unit 16 as operation measurement data (step S2).

After that, the skill level detection means 181 detects the skill level of the driving skill of the user based on the driving measurement data (step S3).
In this step S3, the skill level detection means 181 calculates scores for a plurality of items related to the driving skill, for example, based on the driving measurement data, and detects the skill level of the driving skill of the user based on the total score. To do. Items related to driving technology include, for example, vehicle speed, sudden acceleration/deceleration, and stagger. In this case, the skill level detection unit 181 calculates the vehicle speed based on the route information (described later) transmitted from the server device 20, the position measured by the positioning unit 11, and the time of positioning, and passes the vehicle. A score for the driving speed is calculated based on the difference between the legal speed of the road and the vehicle speed. Further, sudden acceleration (abrupt start) or sudden braking is detected from the value of acceleration in the traveling direction of the vehicle, and the number of times is detected to calculate a score for sudden acceleration/deceleration. Further, the fluctuation or knocking during driving is detected from the value of the acceleration in the lateral direction or the vertical direction that intersects the traveling direction of the vehicle, and the number of times is detected to calculate the score for the fluctuation. Then, the skill level detection means 181 detects the skill level of the user with respect to the driving skill, based on the correlation data between the total score and the skill level stored in the terminal storage unit 16 in advance.

Then, the skill level detection means 181 stores the detected skill level in the terminal storage unit 16 and transmits the skill level to the server device 20 together with the user ID for identifying the user (step S4).
In addition to the skill level, the skill level detection unit 181 may calculate a driving suitability level indicating the degree of safe driving. In this case, for example, it is possible to calculate the driving suitability by the number of sudden starts, sudden accelerations, sudden brakings, driving speed at a corner, excessive speed exceeding legal speed, number of lane changes based on lateral acceleration, etc. it can.

As described above, when the skill level detection process is executed based on the data of the running vehicle and the detected skill level is transmitted to the server device 20, the server device 20 is transmitted at step S4. The transmitted skill level is stored in the user level information of the user information corresponding to the user ID. At this time, when the skill level is already stored in the user level information, the skill level may be updated with the newly acquired skill level, or the acquired skill level may be accumulated and stored.

[Route setting processing]
FIG. 4 is a flowchart showing a route guidance method (route guidance process) in the navigation system 1 of this embodiment.
In the navigation system 1 of the present embodiment, the destination acquisition unit 231 and the current position acquisition unit 232 of the server device 20 execute a point acquisition process for acquiring the destination and the current position (departure point) (step S11). Specifically, in the user terminal 10, when the current position is acquired by the positioning unit 11 and the information on the destination is acquired by the input information acquisition unit 182, the user terminal 10 determines the current position and the destination. The information is transmitted to the server device 20. Thereby, the destination acquisition unit 231 acquires the received destination, and the current position acquisition unit 232 acquires the transmitted current position as a departure place. The acquisition of the current position by the current position acquisition unit 232 is continuously executed.

When the point acquisition process in step S11 is executed, the skill level acquisition unit 233 determines, based on the user information stored in the storage unit 22, the skill level of the user's driving skill recorded in the user level information (for example, “ Skill level information of "high", "medium", or "low") is acquired (step S12).
In addition, the parking lot information acquisition unit 236 acquires the parking lot information of the destination from the data device such as the parking lot management server via the Internet, for example, and extracts the entrance information from the acquired parking lot information (step S13).
As described above, the entrance information may be stored in the storage unit 22 in association with the map information. In this case, the facility information corresponding to the destination is calculated from the map information stored in the storage unit 22. Is acquired, and the entrance information associated with the facility information is acquired.

Then, the route search means 237 executes the route search process according to the skill level of the user acquired in step S12 (step S14).
For example, when the user's skill level is “low”, the route searching means 237 extracts link information whose road width is less than the first threshold value (for example, 5 m) from the road information in the map information, and sets the departure point ( Search the route from the current position) to the destination. As a result, it is possible to guide a route through a wide road excluding narrow roads that are difficult to pass each other. In addition, a route that requires a right/left turn may be excluded when there is no signal in the node information at the right/left turn point. In this case, it is possible to exclude a route that does not easily join the main road because there is no signal. Further, the number of lanes included in the link information is equal to or larger than the second threshold value (for example, 3 or more), and a route that needs to be changed over a plurality of lanes within a predetermined distance (for example, 100 m) may be excluded. ..
On the other hand, when the user's skill level is “high”, the route searching means 237 searches for a route to a destination that is likely to reach the destination in the shortest distance or the shortest time regardless of the road width or the like. To execute.

In addition, in the present embodiment, the route search is performed based on the parking lot entrance information acquired in step S13, and the route search means 237 enters the parking lot in the right turn entry (or in the right traffic area, the left turn entry). ) If prohibited, turn left at the parking lot (turn right if left turn admission is prohibited) and search for an available route.
Here, the route search means 237 searches for a route according to the skill level in the parking lot where the right and left turns can be entered. In other words, when the skill level is “high”, the route searching means 237 searches for a route that reaches the destination shortest regardless of whether the vehicle turns right or left at the parking lot. Further, when the skill level is “low”, the route searching means 237 searches for a route at the left turn entry (right turn entry in the right-hand traffic area) even if the parking lot can be turned to the right or left. Further, when the skill level is “medium”, the route search means 237 may change the route based on the traffic congestion information acquired by VICS (registered trademark) or the like. For example, when the route-related information such as VICS includes information indicating that the road in front of the destination parking lot is congested, or when traffic congestion is predicted based on statistical data of past traffic conditions, the arrival time is determined. If there is a possibility that the road in front of the parking lot will be congested, a left turn (right turn in the right-hand traffic area) to the parking lot is searched for an enterable route.
In addition, the route search means 237 calculates the estimated arrival time at the destination after performing the route search according to the skill level of the user as described above.

After that, the weather acquisition unit 234 acquires the weather information (for example, rain) of the destination or each point (route point) on the route to the destination from the server including the database that stores the weather information of each place. Step S15). Specifically, the weather acquisition unit 234 receives the maximum temperature from the server in addition to the current weather (clear, cloudy, rain, etc.) at the destination or the waypoint, the expected arrival time (the waypoint is expected to pass), and the maximum temperature. , The minimum temperature, the amount of snow, the presence or absence of flooding, the wind speed, the amount of pollen scattered, and the like are acquired and stored in the storage unit 22.

After that, the guidance output unit 238 sets a guidance notification point to notify guidance information to the route searched in step S14 (step S16).
Specifically, the guidance output unit 238 sets the guidance notification point according to the skill level. For example, when the skill level is "low", the guide information (eg, "The next traffic light is right") that guides the target point such as an intersection on the route is early timing (for example, 300m before the target point). Is preferable, and a user with a high level of skill may find it annoying to inform the above guide information at too early a timing, so that it may be annoying at a late timing (for example, 100 m before the target point). Notification is preferable. Further, when the guidance information is notified at an early timing, such as when the skill level is “low”, it is preferable to notify the guidance information a plurality of times because it is far from the actual target. That is, when the skill level is "low", the notification frequency of the guidance information is increased.
For example, when the skill level is “low”, 300 m, 200 m, and 100 m in front of the target point such as an intersection are set as the guide notification points that guide the target point, and when the skill level is “medium”, the target point is set. 200 m and 100 m in front are set as guide notification points for guiding the target point, and if the skill level is “high”, 100 m in front of the target point is set as the guide notification point for guiding the target point.

Further, the guidance output unit 238 detects a road section in which the distance between the guide points is equal to or more than a predetermined distance in the set route. Then, the guidance output unit 238 sets the information providing point according to the distance of the road section when the skill level is “low” or “middle”. This information providing point is set more as the distance of the road section becomes longer. For example, if the road section is less than 2 km, it is not set, and if the road section is 2 km or more and less than 10 km, a point obtained by dividing the road section into two parts (for example, 2.5 km when the road section is 5 km) is set. When it is set as an information providing point and the road section is 10 km or more and 20 km, a point obtained by dividing the road section into three (for example, 4 km points when the road section is 12 km, 8 km points) is set as the information providing point.

After that, the guidance output unit 238 transmits the route (route information) set in step S14 to the user terminal 10 (step S17).
When the route information is transmitted from the server device 20, the user terminal 10 causes the display unit 12 to display the route, estimated arrival time, and the like included in the route information. Then, when the user operates the input operation unit 13 and inputs an operation signal to start the route guidance, the user terminal 10 transmits a request signal requesting the start of the route guidance process to the server device 20. When the server device 20 receives the request signal, the guidance output unit 238 executes the guidance process (step S18). In this guidance process, the user terminal 10 measures the current position by the positioning unit 11 in a predetermined cycle and transmits the measured current position to the server device 20.

[Information processing]
FIG. 5 is a flowchart showing details of the guidance process (step S18) in the navigation method of this embodiment.
First, when the route guidance process in step S18 of FIG. 4 is started, the guidance output unit 238 determines that the current position continuously acquired by the current position acquisition unit 232 is the guidance notification point set in step S17. It is determined whether or not there is (step S21).
When it is determined to be YES in the determination process of step S21, that is, when it is determined that the current position is the guidance information notification point on the route, the guidance output unit 238 guides the corresponding target point (intersection or the like). The information is transmitted to the user terminal 10 (step S22).
Thus, when the user terminal 10 receives the guidance information, the notification control unit 183 controls the display unit 12 and the voice output unit 15 to notify the guidance. For example, when a voice message corresponding to the guide information is output from the voice output unit and detailed information (enlarged view) of the target point (intersection) is provided in the guide information, an enlarged view of the target point is displayed on the display unit 12. Display it.

FIG. 6 is a diagram showing an example in which the guidance information M3 is displayed on the route guidance screen SC1.
When the guide information output by the process of step S22 is received by the user terminal 10, the notification control means 183 of the user terminal 10 displays the route guide screen SC1 as shown in FIG. On the route guidance screen SC1, a current position mark P1, a route L3 to a destination, and guidance information M3 in which the user is traveling are displayed. In this guidance information M3, a message M31 such as "The next traffic light is right" is displayed.
Further, this message M31 is voice-output from the voice output unit 15. Thereby, the proficiency levels are “low”, “medium”, and “high”, that is, all users can recognize the guide information M3 at different timings. As a result, the user can travel on the route based on the guidance information M3 without feeling stress, regardless of the skill level.

On the other hand, when the determination process of step S21 determines NO, the guidance output unit 238 determines whether the skill level of the user is “high” (step S23).
Then, when the determination process of step S23 determines NO, the guidance output unit 238 indicates that the current position continuously acquired by the current position acquisition unit 232 is the information providing point set in step S17. It is determined whether or not (step S24).

If YES is determined in step S24, it is determined whether or not the weather information has been notified (transmitted by the user terminal 10) (step S25). If NO in step S25, the guidance output unit 238 transmits the weather information acquired in step S15 to the user terminal 10 (step S26).

FIG. 7 is a diagram showing an example in which the weather information M1 is displayed on the route guidance screen SC1.
When the weather information output by the process of step S26 is received by the user terminal 10, the notification control unit 183 displays the route guidance screen SC1 as shown in FIG. On the route guidance screen SC1, the current position mark P1 indicating the position of the user terminal 10 (vehicle on which the user terminal 10 is mounted), the route L1 to the destination, and weather information M1 of the destination are displayed. In this weather information M1, an illustration M11 showing the weather of the destination and a message M12 adapted to the weather of the destination are displayed. For example, in the weather information M1, an illustration M11 of rain indicating the weather of the destination and a message M12 such as "The weather of the destination is rain. It is recommended to drive at 50 km or less!" are displayed.
Further, this message M12 is output by voice from the voice output unit 15. As a result, a user whose skill level is “low” or “medium”, that is, the skill level is not “high” can recognize the weather of the destination and the travel suitable for the weather.
Note that the example of FIG. 7 is an example of notifying the weather information of the destination, but the present invention is not limited to this, and may be a waypoint on the route to the destination. For example, when the weather at the time of passing the waypoint is rain, the weather information of the waypoint is notified before passing the waypoint. In this case, the user can recognize the weather at the waypoint before passing through the waypoint.

After step S26, when YES is determined in step S25, and when YES is determined in step S23, the guide output unit 238 causes the route-related information acquisition unit 235 to cause the route-related information to be obtained. Determine if information was obtained. (Step S27).
In the present embodiment, the route-related information acquisition unit 235 refers to the road traffic information distributed from an information distribution station such as VICS or the posted content of the information posting site where the information about the point is posted, and whether or not the route-related information exists. Is constantly monitored. Then, when the road traffic information is acquired, the route related information acquisition unit 235 acquires the content thereof as general traffic information.
Further, the route-related information acquisition unit 235 analyzes the posted contents of the information posting site, searches for posts on roads (names of national roads, prefectural roads, etc.) on the route, and acquires the posted contents of hits. Further, it is determined whether or not the posted content includes a keyword indicating a caution such as speed caution, temporary stop, blind spot, and if the keyword is included, it is acquired as advanced traffic information. That is, the traffic information in which various cautions, which are more likely to be forgotten as the skill level becomes higher, are recorded as the advanced traffic information. On the other hand, when the traffic situation keyword is not included, it is acquired as route introduction information.

In step S27, the guidance output unit 238 determines whether or not the route-related information corresponding to the skill level is acquired. For example, when the skill level is “low” or “medium”, the general traffic information or the route introduction information is determined. Is acquired, it is determined to be YES. Further, when the skill level is “high”, it is determined as YES when the general traffic information or the advanced traffic information is acquired.

Then, if YES is determined in step S27, the guidance output unit 238 transmits the acquired route-related information to the user terminal 10 (step S28).
FIG. 8 is a diagram showing an example in which the route related information M2 is displayed on the route guidance screen SC1. Note that FIG. 8 is an example of the case where the high-level traffic information is transmitted as the route-related information.
When the route-related information output by the process of step S27 is received by the user terminal 10, the notification control means 183 of the user terminal 10 displays the route guidance screen SC1 as shown in FIG. On the route guidance screen SC1, the current position mark P1, the route L2 to the destination, and route related information M2 related to the route in which the user is traveling are displayed. In the route-related information M2, an illustration M21 indicating a position on the route that requires special attention and a message M22 that requires special attention during driving are displayed. For example, in the route-related information M2, an illustration M21 that highlights the position where you should drive with particular attention on the above route, and a message M22 such as "Be careful about the speed near the A signal!" are displayed. To be done. Further, this message M22 is voice-output from the voice output unit 15.
By notifying the route-related information according to the skill level as described above, the user is provided with useful information according to the skill level. For example, by being notified of the high-level traffic information, a user with a high level of skill who tends to have a high confidence in his/her own driving can recognize the position to drive on the route L2 with particular attention, and can recognize an accident or the like. The incidence can be reduced. In addition, since users with skill levels of "medium" and "low" are careful about driving, it does not matter even if the above-mentioned advanced traffic information is not reported, but useful information on the route (for example, in stores) Information etc.) can be obtained. In addition, the general traffic information is notified regardless of the skill level, so that the user can recognize the information about the traffic condition such as the traffic jam and the accident, and the useful information can be obtained when the vehicle is traveling.
The route-related information M2 does not have to be one, and may be two or three. In this case, the second route-related information may be displayed when the position indicated by the route-related information M2 is passed, or may be displayed simultaneously.

Returning to FIG. 5, after the process of step S22, after the process of step S28, and when it is determined to be NO in step S27 or step S24, the guidance output unit 238 determines whether the current position is near the destination. It is determined (step S29). For example, the guidance output unit 238 determines whether the current position is within 1 km to the destination (the entrance of the parking lot at the destination). When the determination process of step S29 determines NO, the guidance output unit 238 returns the process to step S21 and repeats the processes of steps S21 to S28.
On the other hand, if it is determined to be YES in the determination process of step S29, the parking lot information acquisition unit 236 acquires the on-site information of the parking lot (step S30). For example, the parking lot information acquisition unit 236 may provide, as the on-site information regarding the site in the parking lot, map information on the site where a parking space (a parking area surrounded by a white line) and the like and availability of the parking lot. , Obtained from the parking management server managed by the facility set as the destination. If the parking lot information (site information) cannot be acquired in the process of step S30, the process of step S35 described below is performed.

Then, the guidance output means 238 determines whether or not there is a vacancy in the parking lot at the destination by the processing of step S30 (step S31).
If the determination process of step S31 determines NO, the guidance output unit 238 executes route guidance to another parking lot (step S32). In this step S32, a list to another parking lot may be transmitted to the user terminal 10 and the parking lot selected by the user may be reset as the destination. Alternatively, the parking lot closest to the destination may be automatically selected. When automatically selecting a parking lot, a route according to the skill level is searched for by the same processing as step S14.
When the destination is changed to another parking lot in step S32, the process returns to step S21.

On the other hand, if YES is determined in step S31, the guidance output unit 238 determines whether the user's skill level is "high" (step S33).
If NO in the determination process of step S33, that is, if the user's skill level is “low” or “medium”, the guidance output unit 238 outputs the parking lot information according to the skill level to the user. The data is output to the terminal 10 (step S34).
Specifically, when the skill level is "medium", the parking lot information (site information) indicating only the position of the empty parking space is transmitted to the user terminal 10.
On the other hand, when the skill level is "low", the route searching means 237 searches the position of the empty space to the empty parking space where parking is easy, and the route (internal route) , The site information and the user terminal 10. As a parking space that is easy to park, for example, the parking difficulty information is stored in association with the position of each parking space in the site information. As a result, it is possible to easily determine which of the empty parking spaces is the easiest to park.

FIG. 9 is a route guidance screen SC1 when the user's skill level is “low”, and FIG. 10 is a route guidance screen SC1 when the user skill level is “medium”.
In the user terminal 10, when the current position measured by the positioning unit 11 is located in the vicinity of the destination parking lot, the notification control unit 183 of the user terminal 10 indicates that the user's skill level is “low”, and FIG. The route guidance screen SC1 as shown in is displayed. On this route guidance screen SC1, in addition to the current position mark P1, the route L4 to the destination, guidance information M4 including parking lot information (callout information when entering the parking lot), and the availability of the parking lot are notified. The blank information M5 is displayed.
When the skill level is “low”, as the route searched in step S<b>14, the left-turned entry route is guided even if the vehicle can be entered at the entrance of the parking lot by both right and left turns. Therefore, as shown in FIG. 9, as the guide information M4, for example, a message such as "It is difficult to turn right at the parking lot entrance of D mall. To make a detour, go straight ahead at the signal." .. Further, this message is output by voice from the voice output unit 15. As a result, the user having a low skill level can easily recognize the route L4 that can be entered on the route guidance screen SC1.
Further, the sky information M5 displays, for example, a message such as "the D parking lot is empty". The sky information M5 does not have to be a message, and may simply display a mark indicating the vacancy of the parking lot.

On the other hand, the notification control unit 183 of the user terminal 10 displays the route guidance screen SC1 as shown in FIG. 10 when the skill level of the user is “medium”. On the route guidance screen SC1, only the current position mark P1, the route L5 to the destination, and the sky information M5 that informs the availability of the parking lot are displayed. Since the skill level of the user is “medium”, the route searching means 237 searches for the shortest route L5. For this reason, a user with a "medium" skill level can enter the parking lot at the shortest distance.

FIG. 11 is a diagram showing the on-site guidance screen SC2 when the user's skill level is “low”.
When the parking lot information is transmitted to the user terminal 10 by the process of step S34 and the current position measured by the positioning unit 11 moves into the parking lot, the notification control unit 183 of the user terminal 10 indicates that the user's skill level is “low”. In the case of “”, based on the parking lot information transmitted from the server device 20, the on-site guidance screen SC2 of the parking lot as shown in FIG. 11 is displayed on the display unit 12. On the site guidance screen SC2, a current position mark P1, an empty mark M6 indicating a vacant parking space, and an on-site route L6 to a parking space that is easy to park among available parking spaces are displayed. To be done.

For example, of the parking spaces Ar1 and Ar2 in which the empty mark M6 is displayed, the distance in front of the parking space Ar1 is larger than the distance in front of the parking space Ar2. That is, a user with a low degree of skill is more likely to park the vehicle in the parking space Ar1 than in the parking space Ar2. Therefore, the on-site route L6 to the parking space Ar1 searched by the route searching means 237 is displayed on the on-site guidance screen SC2.
In the present embodiment, the in-site route L6 is displayed, but the present invention is not limited to this, and a parking space that is easy to park may be displayed in color, or a special mark is displayed. You may do it.

In addition, such an on-site guidance screen SC2 is displayed on the display unit 12 when the user's skill level is “low”. That is, when the user's skill level is "medium", only the position of the empty space is displayed, and the intra-site route is not displayed. When the skill level is "high", the on-site guidance screen SC2 is not displayed. However, the present invention is not limited to this. For example, even when the skill level is “high”, only the empty space may be displayed as in the case where the skill level is “medium”. At this time, for example, when the user's skill level is “high”, the ease of parking may be ignored and the user may be guided to a parking space near the entrance of the facility.

Returning to FIG. 5, after step S34, the guidance output unit 238 determines whether or not the vehicle has arrived at the destination (step S35). For example, the guidance output unit 238 determines whether or not the current position matches the destination. When NO is determined in this step S35, the process is returned to the step S29, and the processes of the above steps S29 to S35 are repeatedly executed.
On the other hand, when the determination process in step S35 is YES, the guidance output unit 238 ends the route guidance process.

[Effect of Embodiment]
The navigation system 1 according to this embodiment has the following effects.
In the present embodiment, guidance information corresponding to the user level information including the user's skill level of driving skill is notified. According to this, the guidance information according to the user's skill level of driving skill is notified. Such guide information is highly likely to be useful information for the user, and can provide the optimum guide for the user.
For example, when the guide information is notified without considering the user level information including the skill level of the user's driving skill, information unnecessary for the user may be notified as the guide information. On the other hand, in the present embodiment, since the guidance information is notified according to the user level information including the skill level of the user, the guidance information is highly likely to be useful information for the user. Therefore, the user can effectively use the guidance information and can safely drive the vehicle.

In the present embodiment, the position of the guidance information notification point is changed depending on the skill level, so that the notification timing of the guide information is changed depending on the skill level. Therefore, the degree of skill is “low”, “medium”, and “high”, that is, all users can recognize the guide information M3 at different timings. As a result, the user can travel on the route based on the guidance information M3 without feeling stress, regardless of the skill level.

Since the route searching means 237 executes the route searching process according to the user's skill level acquired in step S12, for example, a user with a low skill level is a narrow road or a signal without a center line. Because there is no road, you cannot be guided about a road that is difficult to merge or a road that requires you to change lanes in a short period of time, so even users with a low level of skill can operate the vehicle with peace of mind. In addition, a user with a high level of skill will find a route to a destination that is likely to reach the destination in the shortest distance or in the shortest time without excluding any road that is difficult for beginners. Since the search is performed, a user with a high skill level can reach the destination in the shortest distance or the shortest time. Therefore, user convenience can be improved.

In the present embodiment, the route-related information according to the skill level is notified, so that the user is provided with useful information according to the skill level. For example, by being notified of the high-level traffic information, a user with a high level of skill who tends to have a high confidence in his/her own driving can recognize the position to drive on the route L2 with particular attention, and can recognize an accident or the like. The incidence can be reduced. In addition, since the users with the "medium" and "low" skill levels are careful about driving, it does not matter if the above-mentioned advanced traffic information is not reported, but useful information on the route (for example, Store information, etc.) can be obtained. In addition, the general traffic information is notified regardless of the skill level, so that the user can recognize the information about the traffic condition such as the traffic jam and the accident, and the useful information can be obtained when the vehicle is traveling.

Since the parking lot information acquisition unit 236 acquires the entrance information of the parking lot of the destination, the route search unit 237 can execute the route search with the entrance as the destination. According to this, the user can be surely guided to the destination.
Further, since the entrance direction of the entrance (for example, right turn prohibition, left turn prohibition, etc.) can be acquired, for example, when there is no particular restriction on the entrance direction of the parking lot entrance, the entrance direction of the parking lot can be increased according to the skill level of the user. You can change the route. According to this, users with low skill level are informed (displayed) of routes that can easily enter the parking lot, and users with low and medium skill levels are in the shortest distance. Since the route that can be entered is notified, the convenience for the user can be further enhanced.

In the user terminal 10, the parking lot information acquisition means 236 has acquired the information on the site of the destination parking lot (map information on the site where the parking space and the like are displayed, availability of the parking lot, etc.) Since the information is displayed on the display unit 12, the user can easily recognize the parking information of the destination. Further, since the displayed parking lot information varies depending on the skill level of the user, any skill level user can use the navigation system 1 without stress.

Particularly, when the user's skill level is "low", it is easy to park the route guidance screen SC1 according to the user's skill level, and an empty mark M6 indicating that the parking space is vacant and the available parking space. Since the on-site route L6 that guides various parking spaces is displayed, even a user with a low level of skill can easily park a vehicle in the parking space.
Further, when the vehicle on which the user terminal 10 is mounted reaches within a predetermined distance range from the destination, the on-site information including the space information is acquired, so that the current situation of the parking lot can be more surely grasped. it can.

Since the user terminal 10 displays the route guidance screen SC1 including the weather information acquired by the weather acquisition unit 234 on the display unit 12 and outputs the weather information by voice, the skill levels are “medium” and “low”. The user of “” can recognize the weather of the destination and traveling suitable for the weather. Further, since the weather information is not notified to the user having a high degree of skill, the user can drive the vehicle without recognizing the information that is likely to be unnecessary. Therefore, convenience for all users can be improved.

[Modification of Embodiment]
It should be noted that the present invention is not limited to the above-described embodiments, but also includes the following modifications within a range in which the object of the present invention can be achieved.
[Modification 1]
In the above-described embodiment, the route search unit 237 searches for a route according to the user's skill level acquired by the skill level acquisition unit 233, and the guidance output unit 238 determines the user based on the route according to the skill level. The vehicle equipped with the terminal 10 is guided to the destination. However, the present invention is not limited to this. For example, the route according to the skill level may be changed by the user's operation.

FIG. 12 is a diagram showing an example of the route guidance screen SC1 displayed on the display unit 12 when the user's skill level is “low”.
When the route information is output from the guidance output unit 238 to the user terminal 10, the user terminal 10 displays the route guidance screen SC1 as shown in FIG. On the route guidance screen SC1, a current position mark P1, a route L7 corresponding to the skill level “low”, and a level UP request button BT1 are displayed. The level UP request button BT1 displays the route L8 searched when the skill level higher than the current skill level of the user (for example, if the current skill level is “low”, the skill level is “medium”). It is a button. When the level-up request button BT1 is selected by the user operation, the user terminal 10 sends a level-up request to the server device 20. As a result, the route search means 237 of the server device 20 searches for the route L8 to the destination according to the skill level “medium”. Then, the guidance output unit 238 outputs the route information indicating that the route L8 is displayed on the route guidance screen SC1 of the display unit 12 to the user terminal 10 together with the route L7.
According to this, the user can recognize the route L8 that is one step higher than the skill level of the driving skill of the user. Therefore, if the user determines that traveling on the route L8 is possible, he/she may travel on the route L8, and if it is still difficult, the user may travel on a route according to his/her skill level “low”. Therefore, it can contribute to the improvement of the skill level of the user's driving technique.

In addition, in the modification 1, the level UP request button BT1 is displayed on the route guidance screen SC1. However, the present invention is not limited to this. For example, the level UP request screen may be displayed at any timing. In this case, not only the route but also the notification timing of the guidance information and the type of information displayed as the route-related information may be changed. According to this, the user can recognize the guidance information, the route guidance information, and the parking lot guidance information that are notified to the user of the skill level one step higher. Therefore, is the current skill level of the driving skill suitable? You can judge whether or not. For example, when the above-mentioned various kinds of information obtained by increasing the skill level of the driving skill by one step are suitable for oneself, the skill level of the driving skill may be increased by operating the input operation unit 13. According to this, various information suitable for the user can be notified.

[Modification 2]
In the above-described embodiment, an example is shown in which guidance is provided according to the user's skill level in driving skill, but the present invention is not limited to this.
For example, a configuration may be adopted in which road environment information that is a strength and a weakness of the user is set and input at the user terminal 10 and the traffic environment is transmitted to the server device 20. As the road environment information, as described above, the road, parking lot, weather, time zone, etc. can be exemplified. For example, the unfavorable roads are "roads, heavy traffic roads, high-traffic roads, and mountain roads", unfavorable parking lots are "parallel parking spaces", unfavorable weather is "snow, dense fog", You can enter "midnight" as your favorite time zone. In this case, even if the skill level is “high”, the route search means 237 searches for a route similar to the case where the skill level is “medium” when there is a road whose condition matches the environmental information of the weak user. May be carried out. Also, as the route guidance information and the weather information, information with a low degree of skill may be provided.
In addition, such information of the strengths and weaknesses is not limited to information manually input by the user, and, for example, the server device 20 actually drives the user terminal 10 from a driving route or time zone, weather at that time, and the like. Is acquired and stored in the storage unit 22. Then, based on the accumulated driving history, the road environment information and the like that the user prefers (is good at) may be statistically determined.

Furthermore, in the above-described embodiment, the user information may include a base such as a home or a work place, other registration points, and the like, and an active area centered on the base or the registration point may be stored. In this case, the route to be searched, the guidance information to be notified, the route-related information, and the weather information may be changed depending on whether the area is within the predetermined distance range around the base or outside the active area. In other words, in areas such as travel destinations that you visit for the first time, even if you have a high level of skill in driving technology, there is a high possibility that you will not be familiar with road conditions, and the driving attitude of other vehicles (for example, average High speed, short inter-vehicle distance, departure and stop timing for traffic signals, etc.) may differ. Therefore, in addition to the above-mentioned skill level of the driving technique, the route guidance processing according to the skill level described in the above embodiment is performed in the active area depending on whether or not the route to be searched is in the active area. In the outside of the activity range, the level of skill may be lowered by one and the route guidance processing of the above-described embodiment may be performed.
In addition, for example, when moving from the active area to the outside of the active area, when moving from the outside of the active area to the inside of the active area, when sandwiching the active area or the area outside the active area in the middle of the route, when the skill level is high in the active area It is also possible to perform the route setting and the notification of various information, and perform the route setting and the notification of various information in which the skill level is reduced by one step outside the active area.

In addition, in the above-described modification, the skill level is decreased by one level for the outside of the activity range, but the process may be performed such that the skill level is increased by one level for the activity range and the route setting and various information are notified. .. In this case, the user with low or medium skill level is notified of the route and information at a level one step higher than the current skill level within his or her activity range, so that the user's driving skill is improved. It can contribute to improvement of skill level. In addition, since it is within the range of activity, for example, in an area where there is no sense of land, it is possible to challenge the improvement of the driving skill with more peace of mind than in the case where the guidance of the skill higher than the current skill is notified.

[Modification 3]
In the above embodiment, the skill level detection unit 181 of the terminal control unit 18 detects the skill level of the user's running technique based on the acceleration detected by the sensor unit, the attitude of the user terminal, the transition of the current position, and the like. And However, the present invention is not limited to this. For example, the skill level detection unit 181 acquires travel record data from the communication unit of the vehicle in which the user terminal 10 is mounted via the terminal communication unit 14, and detects the skill level based on the travel record data. You may
Specifically, from the travel record data acquired from the vehicle, the user's skill level is set to "high" or "medium" based on preset criteria such as the vehicle traveling speed, accelerator pedal depression amount, brake pedal depression amount, and steering speed. , And “low”. For example, a less skilled user has a larger amount of brake depression and a greater change in traveling speed than a highly skilled user. Users with large changes are categorized as "low" and users with extremely small changes in brake pedal amount and running speed are categorized as "high". It may be classified as “medium”. Further, since a user with low skill level tends to have a rapid increase in the accelerator pedal stroke and a higher steering speed than a user with high skill level, the skill level detection means 181 uses the accelerator pedal The user's skill level in which the amount tends to increase rapidly and the steering speed tends to be high is classified as "low", and the skill level of users who tend to increase the accelerator pedal slightly and the steering speed tends to be low. You may classify into "high" and classify the skill level of the user located in the middle of these into "middle".

Further, the detection of the skill level is not limited to the traveling speed of the vehicle, the amount of accelerator depression, the amount of brake depression, and the steering speed, and for example, the fuel consumption of the vehicle, the degree of tire wear, the traveling time, the traveling distance, the traveling time zone, the traveling It may be detected based on the number of days, the day of the week, or any other standard.
In addition, the detection of these skill levels may be executed by a control unit provided in the vehicle. In this case, the terminal control unit 18 of the user terminal 10 may transmit the skill level (skill level information) acquired from the vehicle to the server device 20, or the skill level acquired from the vehicle and the above embodiment.
